GetWebP vs Sharp：零依赖替代方案

import sharp from 'sharp';
import fs from 'fs/promises';
import path from 'path';

// Convert every image in a directory to WebP
const dir = './images';
const out = './out';

const files = await fs.readdir(dir);
const images = files.filter(f => /\.(jpe?g|png|gif)$/i.test(f));

await Promise.all(
  images.map(file =>
    sharp(path.join(dir, file))
      .webp({ quality: 80 })
      .toFile(path.join(out, file.replace(/\.[^.]+$/, '.webp')))
  )
);

# One command — that's it
getwebp ./images -o ./out
